Letters Patent No. 103,292, dated May 24, 1870.

IMPROVEMENT IN HOISTI NG APPARATUS.

The Schedule referred to in these Letters Patent and making part of me name.

To olt whom it may concern:

Belit known that I, Gnonon W. BROWN, of the city andState of New York, have invented and made a new and useful Improvement in Hoisting Appara- 1 tus for Buildings; and the-following is declared to be a correct description thereof.

In the construction of huildings, it' has been usual to employ men to carrythe bricks and mortar up ladders to supply the masons in their work.

To avoid the cost of this tedious manual labor, a hoisting apparatus has been devised to be operated a by steam or horse power.

In some cases this apparatus has been constructed. for the particular building, and in other cases, temporary or portable hoistqvays have been fitted up, but in consequence of the space occupied, the difficulty of application, the costliness, or the risk of injury from the same to tlie'workmen, such portable hoisting apparatus has met. with but-little favor, especially in the erection of ordinary buildings.

My invention is devised with aivicw to portability,

compactness, andease of application, so as to he railable in buildings generally.

after the walls of the building have been run up.

-In the drawing-' A Figure 1 is an elevationillustrating the manner in which this apparatus is employed.

Figure 2 is a cross-section of thehoisting-platform; and

Figure 3 is a section, in

larger size, of the connec- In constructing buildings, the foundation and first tier of beams are to be, prepared in the usual manner, also the walls for the first story above the street,

and in the sccon d tier of beams, at a convenient place, one beam is to beleft out or slid aside from position, except in cases. where a stair-way or hoistway can be availed of, so as to put up the tubular slides for the platform.

These tubular slides a are made of wrought-ir0n pipes, in sections of convenient lengths, and I employ a connection or coupling-block, 71, between the respective lengths.

these blocks has a projecting flange to be attached by a spikeor otherwise to a cross bearer or block,

d,.placed upon the beams e or other convenientsupport.

These tubular slides, it will now be seen, are not interrupted by any inward projections, hence become a reliable guide for notches upon the ends of the platform f, and these tubular slidescan be extended from story to story, as the buildingprogresses, and the upper ends of the tubes project into onpass through the head-piece g of th'e'movable frame ht that is to be lifted from one floor 'to another as'the' tiers of beams are laid, so as to form a support'fon the upper ends of the tubes and allow the platform" 1.

to be drawn up to the level of. the upper tier of beams. v

The platform f has a central bearer, k, against which the sides of the hods are laid, as shown in fig.

2, and the length of this platform fand bearer k is to be such as to contain two or more hods, and in this manner hods, some with bricks and others with mortar, in the proper proportion, can be drawn up to the top floor and taken off by a set of men who successively stand upon the platform a previously emp- I 'vent the hods slipping, and the edge of the platform should have a ledge or rim to retain the lower ends of the shanks or handles of the hods.

In this construction, the hodscan be handled without the carriers stepping upon the platform, hence, risk of personal injury by the fall of the platform is avoided. M;

What I'claim as my invention is- 1. The tubular slides for the hoisting apparatus, formed in sections :to he set together and secured in the building, substantially as specified.

2. The blocks 1), constructed as set forth, and employed for connecting the sections of the tubular slides and securing them in place, as specified.

3. The movable frame g h t and platform f, in combination with the aforesaid; tubularslides, substantially as-and for the purposes specified.

Signed by me this 5th day of April, A D. 1870.

GEO. W. BROWN.
